WINDOW-SHADE FIXTURE.

Patented April 2, 1907.

Application filed December 31, 1906. Serial No. 350,126.

T0 to whom it may concern: I

Be it known that I, SOREN ROBERTSON Sxov, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and l State of Ohio, have invented certain new and useful Improvements in IVindow-Shade Fixtures and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in window-shade fixtures; and the object of the invention is to provide a convenient, noiseless, and serviceable fixture adapted more particularly to be used in passenger-cars and wherever side guides are desirable and which is so constructed that the shade can be raised and lowered to any desired elevation and held there by its own fixture, and that no portion of the fixture can be pulled or pushed out of place when the shade is raised or low ered, all substantially as shown and de scribed, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation. of a portion of a window shade or curtain supported upon my improved fixture, which is in working position in a section of a window-frame. Fig. 2 is a perspective view of the fixture complete; and Fig. 3 is a section on line 8 3, Fig. 1.

I am of course aware that various devices have been made and patented from time to time having the same general object in view as this invention, and I am also aware of specific constructions for this purpose in which there are supporting cross-pieces and arms connected therewith, both spring and rigid and adapted to run in the side frame or casing of a window, and other devices having arms adapted to engage cords or wires stretched in the window-frames and having In fact, I am aware of many different de vices designed to be used more or less after the manner or for the purpose of the present invention; but I am not aware of a fixture having the novel construction and advantages in operation found in the present invention, as will now more clearly appear.

It will be observed, first, as a differentiating and original fixture that the fixture or suppost consists of practically only three parts, in which cross-piece B is the carrying or supporting member and the substantially T- shaped ends 0 are the working chambers of the device adapted to slide in the side rails of window casing or frame D. The said casing or frame D, or rather the sides thereof, are provided with channels d, having parallel walls vertically, and the arms 0 of the respective end members O run in these channels against said side walls. It is to be observed also that the said end members are unitary, practically being T shape as a whole and each having a supporting portion or stem 2 projected into cross-bar B, and said arms 0 are essentially spring-arms rigid with said stems if not integral therewith and shown as having split spring extremities providing lateral spring-bearings 4 for engagement with the side walls of said grooves or channels at of the window-frame.

The natural tendency of bearings 4, with their spring-shanks, is to spring apart, so that they make tight frictional contact with the side walls of channels (1 and always hold this relation. For convenience of manufacture one of said spring portions 4 may be a separate part afiixed to the main portion of said arm. This makes a noiseless engagement of the fixture in the window, in which there can be no rattling or shaking of the fixture, and the frictional engagement is maintained wherever the fixture may be drawn or placed. The spring-arms c adapt the bearings 4 to run in sinuous or crooked channels, and the said end pieces O are set, with their supports 2, into cross bar or member B at such length as to make the engagement perfectly rigid when tightened. Bar B is shown as being substantially flat-sided, but spaced apart between its sides, into which the said stems are inserted, one side lengthwise, if preferred, for cheapness of construction. Otherwise both sides might be closed. The arms c are entered through slots 9 in the ends of the bar, and said end parts C have a limited adjustment, so as to be able to place the fixture in a window and to remove it therefrom by adjusting the said pieces C to the width of the window, what ever it may be, within limits. To these ends cross-piece B has slots 6 in its side, and setscrews 7 engage with stem 2 through said slots for adjustment as may be found convenient. When the device is set in a window, no further adjustment thereof is required, and the device is permanently in place for use. The curtain or shade E can. then be afiixed if not already secured to the fixture.

A further and important feature of this invention is the construction and working relation of cross-bar B, which is designed to have its own ends in engaging relation in channels (Z of the window-frame in addition to supporting-arms c in said channels. The said ends b are therefore made of such depth laterally or between sides as will accommodate said ends to the width of channels (1 and make a comfortably close engagement therein. This both simplifies and improves the construction of the bar which carries the curtain or shade and which in any event should be firmly confined at its ends whatever the engagements above or below may be. When fastened together, the fixture becomes prac tically a rigid unit of H shape, the same as if it were one piece, and if moved up or down all parts must move together and cannot bind nor get displaced at any point.

Another distinguishing peculiarity of this fixture is the split or divided extremities of the spring-arms, whereby said ends provide frictional locks and antirattling connections for the fixture in the window. This is re garded as a most valuable improvement in this art, because of the important dual function which the said divided bearings perform. It will be seen also that the arms 0 are flat and extend edgewise into channels (I, so that if one were to grip the cross-bar near one side of the window to raise the curtain it would be impossible to throw that side up and twist or distort the fixture without really moving the curtain or shade, because as to such action the said arms are absolutely rigid and could not be bent nor thrown out of their channels. This further shows that the fixture is, in fact, a rigid frame for all practical purposes, though arms 0 do spring or yield to sinuous courses or where one side of the window is not in alinement with the other. A recess is cut in the side of the window-casing for the introduction of the cross-bar B, and a plate P covers said recess.

What I claim is- 1. As a new article of manufacture, a window-shade fixture having a rigid cross-bar and arms fixed rigidly in the ends of said bar and provided with divided spring-bearings at their ends.

2. A window-shade fixture of substantially H shape having fiat spring-arms provided with split outer extremities adapted to bear laterally against the walls of the window-cas- 3. A window-shade fixture of substantially H shape comprising a rigid cross-bar and flat spring-arms rigidly fixed in the ends of said bar and each of said arms having fiat outer springs in the same vertical plane as said bar adapted to press laterally against the walls of the window-casing.

4. A window-shade fixture comprising a cross-bar and oppositely-projecting flat spring-arms at each end thereof fixed rigidly in the ends of said bar and having divided spring-bearings at their outer ends.

5. A window-shade fixture comprising a rigid cross-bar and substantially T-shaped end pieces having their stems fixed in said bar and provided with spring-arms in the same vertical plane as the ends of said bar, thereby providing three points of bearing at each side of the fixture with the immediate ends of the cross-bar as the central bearin s.

6. A window-shade fixture consisting 0% a rigid tubular cross-bar and two substantially Tshaped members within the ends of said bar and means to adjustably fix said members in working position, and said members having split spring ends adapted to engage fiictionally in the window-casing.

7. A window-shade fixture having a sub stantially tubular cross-bar, substantially T-shaped end members adapted to be rigidly fixed in said bar and having their outer edges substantially in line with the end edges of the bar and the arms of said end members provided with split spring-bearings at their outer extremities.

In testimony whereof I sign this specification in the presence of two witnesses.
